Homework 1.Redraw the following schematics with
the impedance of each of the element shown in
Laplace domain. Then determine the overall
impedance of the entire circuit between the two
ends of the shown circuit and express it in
Laplace domain as a ratio of two polynomials in
s, with the coefficients of the highest power if
s in the numerator and denominator are made
unity. (Follow the method outlined in the lecture
to determine the impedances of elements in
Laplace domain and then use the formulas for
combining impedances in series and parallel.)

Homework 1.   A shiny metal disk with a dark spot
on it, as shown in figure below, is rotating
clockwise at 100 revolutions/second in a dark
room. A human observer uses a strobe that flashes
99 times/second to observe the spot on the metal
disk (a strobe is a flashing light whose rate of
flashing can be varied). The spot appears to the
human observer as if it is rotating slowly 2. (a)
A system samples a sinusoid of frequency 480 Hz
at a rate of 100 Hz and writes the sampled signal
to its output without further modification.
Determine the frequency that the sampling system
will generate in its output.

z-transform from the tables. This will require
some algebraic and /or trigonometric

Homework 1.Find the z-transform x(z) of x(n) .
Hint Follow the method used in the lecture for
Week 6. Also, when evaluating the numerical value
of a trig function, keep in mind that the
arguments of trig functions are always in radians
and not in degrees. 2. Find the system transfer
function of a causal LSI system whose impulse
response is given by and express the result in
positive powers of z. Hint The transfer function
is just the z-transform of impulse response.
However, we must first convert the power of -0.5
from (n - 1) to (n - 2) by suitable algebraic
manipulation.
